TOBACCO PIPE.

;App1icati01i filedMay 7, 1924. Serial No. 711,528.

To all whom it may concern:

Be it known that I, HARRY E. GoLm-oenL. a citizen of the United States otAn'ienic/a, residing at city, county, and State of New York have invented new and useful .lm provements in Tobacco Pipes of which the following is a specification.

My invention relates to tobacco pipes and more particularly to pipes having a mouth piece provided with a removable cleaning device.

An object of the invention is the provision of a pipe of the above described character wherein the mouth piece is reenter-red to rigidly support a removable cleaning attaohment.

A further object ofmy invention is to provide the stem of a pipe with a cleaning attachment, which is entirely concealed within the stem and which will not interfere with the passage of smoke from the bowl to the mouth piece, the cleaner being of such shape that while capable of conducting the smoke it will present scraping or cleaning edges so disposed that by turning the mouth piece any particles adhering to the bore of the stem will be detached and removed.

The invention is illustratively exemplified in the accompanying drawings, in which, Figure 1 is a substantially longitudinal sectional view of a pipe showing the reenforced mouth piece and removable cleaning device; Figure 2 is a transverse sectional view of the pipe taken on the lines 22 of Figure 1; and Figure 3 is a detail view of the cleaning device.

Referring to the drawings the pipe comprises a bowl 10, stem 11 and removable mouth piece 12 having a cylindrical projection or shank 13 removably fitted in the bore 14 of the stem 11.

The mouth piece 12 is constructed preterably of hard rubber or other similar composition, and running axially thereof is a smoke bore 15, which adjacent the shank 13 is increased in size to accommodate an interiorly threaded reenforcing tube 16, comprising a thin gauge metal member, permanently embedded in the hard rubber and extending the full length of the enlarged bore.

The cleaning device 17 is provided with a body portion 18 which is round in cross section and projecting radially thereof is a thereof consists of a slightly tapered z-ylin drical section 21 having a plurality of radi ally drilled passages or smoke conduits 22 WlllCll communicat with an axial bore 23.

-The bore 23 is disposed in an integral sec-- tion of the cleaning device, comprising an annular collar 24 arranged between the tapered section 21 and a reduced exteriorly threaded surface 25 which is adapted to be screwed. into the threaded reenforcing' member 16 of the mouth piece.

The ribs 19 present substantially straight scraping edges so arranged that they virtually contact with the adjacent wall of the bore 14 in the stem 11,' and by turning the mouth piece 12 any particles adhering to the stem will be detached and removed. As shown in the drawing the bore 14 of the stem 11. may be of a slightly smaller diameter at the bowl end than at the open end. in which case the diameter of the ribs is less than that of shank 13. In either construction, howeven. the section of the bore 14 embracing the tape ed section 21 of the cleaner forms a chamber 26 in which the smoke col lects and is given opportunity to expand and cool before being drawn through the passages 22 and bore 23 into the mouth piece 12.

It will be observed, particularly by referonce to the construction shown in Figure 1., that when the mouth piece is being turned the scraping edges are brought into engagement with all portions of the inner wall of the stem 11, thus removing any material which may adhere to the said wall. Furthermore, the tobacco juice and saliva which ordinarily collect in a pipe stem and mouth piece will remain in the chamber 26, while the substantially dry smoke is drawn outwardly through the conduits 22 and 23 and thereafter through the bore 15 of the mouth piece 12.

What I claim and desire to secure by Letters Patent is 1. A smoking pipe con'iprising a bowl, a stem. and a mouth piece removably fitted in the stem, means for reinforcing said mouth piece, and a cleaning device removably mounted in said means and having smokeconducting passages communicating at opposite ends in the stem and mouth piece,

said cleaning device having also longitudinal scraping ribs the spaces between which form smoke-conducting channels communicating at opposite ends With the bowl. and a point adjacent the stem ends of said passages.

2. A smoking pipe comprising a bowl. a stem, a mouth piece removably fitted in the stem a tubular reinforcing member in the bore of said month piece, and a cleaning attachment for said stem comprising a rear section removably disposed in said reinforcing member, a reduced intermediate section, and a forward section having longitudinal ribs constituting scraping edges contacting with the inner Wall of said stem, the spaces between the ribs forming channels for the passage of smoke, and the space between the inner Wall of the stem and said intermediate section 01": the cleaner "forming a cooling and drain chamber.

3. A cleaning attachment as claimed in claim 2, in which the first named section of the cleaning device is exteriorly threaded to screw into the threaded interior of said tubular reinforcing member. 7

In testimony whereof I have alti'xed my signature.
